Novel bridgeless PFC converters with low inrush current stress and high efficiency

摘要

This paper presents novel bridgeless power factor correction circuits that achieve both high reliability and high efficiency. The proposed circuits can protect Silicon Carbide Schottky barrier diodes and MOSFETs against flowing high inrush current without impairing efficiency. This paper introduces the principle of operation including the control scheme and verified performance based on simulation and experimental results.
